Официальное название

A Global Multicenter Phase 1/2 Trial of EO2463, a Novel Microbial-Derived Peptide Therapeutic Vaccine, as Monotherapy, and in Combination With Lenalidomide and Rituximab, for Treatment of Patients With Indolent Non-Hodgkin's Lymphoma

Обзор

The purpose of this study is to define the recommended Phase 2 Dose, safety, tolerability, immunogenicity, and preliminary efficacy of EO2463 during monotherapy and in combination with lenalidomide and/or rituximab in patients with indolent NHL

Подробное описание

For inclusion in Cohort 4b the above applies except that patients with FL, and not patients with MZL, will be eligible for enrollment.
• For inclusion in Cohort 2 patients should have newly diagnosed, previously untreated (radiotherapy as only prior treatment is allowed), biopsy-proven grade 1, 2 or 3A, FL or MZL. ECOG performance status 0 or 1, low tumor burden by Groupe d'Etude des Lymphomes Folliculaires (GELF) criteria, and not be in need of standard of care therapy according to the assessment of the treating physician.
• For inclusion in Cohort 3 patients should have newly diagnosed, previously untreated (radiotherapy as only prior treatment is allowed), biopsy-proven grade 1, 2 or 3A, FL or MZL. ECOG performance status 0 or 1, low tumor burden by GELF criteria and be in need of therapy according to the assessment of the treating physician.
• Patients with an age ≥ 18 years old.
• Patients who are human leukocyte antigen (HLA)-A2 positive.
• Patients should have radiologically measurable disease with a lymph node or tumor mass greater than or equal to 1.5 cm in at least one dimension.
• Males or non-pregnant, non-lactating, females.
• Patients willing and able to comply with the scheduled visits, treatment plan, laboratory tests, and other study procedures indicated in the protocol.
• Patients having received the information sheet and who have provided written informed consent prior to any study-related procedures.

Критерии исключения

• Patients treated with dexamethasone > 2 mg/day or equivalent (i.e. 13 mg/day of prednisone, or 53 mg/day of hydrocortisone) within 14 days before the first EO2463 administration, unless required to treat an adverse event.
• Patients with grade 3B FL or transformation to an aggressive lymphoma subtype.
• Patients with only one prior treatment and a high-risk profile as defined by first progression of disease within 24 months of diagnosis (the exclusion is not applicable for patients with more than one prior line treatment).
• Patients with prior exposure to EO2463.
• Patients treated with immunotherapy (meaning immunostimulatory or immunosuppressive therapy; beside excluded, or allowed, compounds per other inclusion/exclusion criteria specifications), radionuclide therapy, radiotherapy, cytoreductive therapy, or received treatment with any other investigational agent within 28 days before the first EO2463 administration.
• Patients to be included in Cohorts 1 and 4, and who have received rituximab or other B cell ablation therapy within 8 weeks of start of study treatment.
• Patients to be included in Cohorts 4, who received prior CAR T-cell therapy and progressed within 6 months after this therapy.
• Patients with abnormal laboratory values.
• Patients with persistent Grade 3 or 4 toxicities.
• Uncontrolled central nervous system (CNS) metastasis.
• Other malignancy or prior malignancy with a disease-free interval of less than 3 years.
• Patients with clinically significant disease.
• Patients with suspected autoimmune or active autoimmune disorder or known history of an autoimmune neurologic condition (e.g. Guillain-Barré syndrome).
• Patients with history of solid organ transplantation or allogeneic hematopoietic stem cell transplantation.
